不装软件读取Excel内容

DataTable dt = new DataTable();
        string filepath = Server.MapPath("Excel\\data.xls");
        Workbook workbook = new Workbook(filepath);
        Worksheet ws = workbook.Worksheets[0];   // workbook.Worksheets["Sheet1"]  可填写指定表名或者默认第一个表

        Cells cells = ws.Cells;
        int count = cells.Columns.Count + 1;
        for (int i = 0; i < count; i++)
        {
            string str = cells.GetRow(0)[i].StringValue;
            dt.Columns.Add(new DataColumn(str));
        }
        for (int i = 1; i < cells.Rows.Count; i++)
        {
            DataRow dr = dt.NewRow();
            for (int j = 0; j < count; j++)
            {
                dr[j] = cells[i, j].StringValue;
            }
            dt.Rows.Add(dr);
        }
        dt.AcceptChanges();
        BindData(dt);      //显示数据
